Spiritual Conversation

G. I. Gurdjieff (c.1866–1949) was born in Gyumri, Armenia and raised in the Caucasus and eastern Asia Minor. He also traveled extensively throughout Turkey to places of pilgrimage and in search of Sufi teachers. Through the lens of Gurdjieff’s notion of legominism, or the means by which spiritual teachings are transmitted from successive generations, this article explores the continuing significance of spiritual practice and tradition and the ways that these forms remain relevant in shaping contemporary trends in spirituality. Beginning with Gurdjieff’s use of legominism, the article provides reflection on some early findings done in field research in Turkey— through site visits, interviews and participant-observation—conducted in the summers of 2014 and 2015. The aim of the project is both to meet individuals and groups, particularly connected to Sufism, that may have some contact with the influences that Gurdjieff would have been familiar with, and to visit some of the sites that were part of Gurdjieff’s early background and which served to inform his work. Considerations of contemporary practices include the view of spiritual transmission, and practices of pilgrimage, prayer and sohbet, or spiritual conversation, in an ongoing discourse about spiritual transformation.

The expansion of human knowledge in all areas is largely the outcome of the activity of academic institutions and the result of their mission to contribute to the cultural, intellectual and economic development of the society, involving education, research and university extension activities. For many years, the academic community has been organizing itself in all different ways to respond to current and future needs, ensuring research integrity and recognition, and building on successive generations of peers to validate and support the launching and development of novel research streams. We owe the current state of research and development of our society to generations of scholars and scientists that have brought all of us here.(...)

Building on several international professional meetings of architects organized in Romania or abroad, this article details how various modernist principles, traditionally subsumed to Western European culture, were gradually reinterpreted as an object of policy and professional knowledge on urban space in the second and third world countries. The article analyses the dialogue between Romanian architects and their foreign colleagues. It highlights how these conversations adjusted the hierarchies and power relations between states and hegemonic centres of knowledge production. In this sense, it contributes to the recent research on the means by which the "trans- nationalization of expertise" "transformed various (semi)peripheral states into new centres of knowledge and thus outlines a new analytical space where domestic actions of the Romanian state in the area of urban policies are to be analysed not as isolated practices of a totalitarian regime, but as expressions of the entanglements between industrialization models, knowledge flows and models of territoriality that were not only globally relevant, but they also often received specific regional, national and local forms.

Rule Out

Three family members from two successive generations showed a moderate bleeding disorder. The bleeding times (Duke and Ivy-Borchgrevink) were both constantly prolonged. Platelet aggregation induced by ADP and adrenaline showed no second wave; collagen at low to moderate concentrations failed to aggregate and release ATP whereas higher amounts aggregated and released. Aggregation and release due to thrombin, ristocetin and synthetic epoxy derivatives (U 44069 and U 46619) were normal. Arachidonate (A.A.) was inactive and was not converted into thromboxane (TX) A2 activity evaluated on the rabbit aorta strip. The patient’s platelets did not respond to A.A. when PRP from an aspirin treated control was added. Platelet phospholipids (PL) were labelled by 14C - A.A. before stimulation by thrombin (T). Radioactivity of the PL of the propositus' platelets was affected with T to a similar extent as 5 laboratory controls, indicating that the phospholipase activity was not impaired. In contrast, no TXB2 was found: 0.9 p. cent as compared to 6 p. cent of total radioactivity in controls.Our data suggest a deficit in cyclo-oxygenase particularly since the levels of PGE2, PGF2a and PGD2 were within the limits of detection. These results seem to rule out the possibility of a TX-synthetase deficiency with excessive production of anti-aggregating PGs. This study suggests that transmission is autosomal dominant and confirms that cyclo-oxygenase is not needed for aggregation and ATP-release by high amounts of collagen.

Loosely Coupled

A small-world simulation model of a regional innovation system combining the strength of the intersubject relationship of the regional innovation system with the loosely coupled system is constructed. We use a simulation to observe knowledge flow within the regional innovation system under relationships of varying strength. The results show that when the relationship between the subjects of the regional innovation system reaches a certain strength, the system will exhibit high module independence and high network integrity, forming a loosely coupled system. The knowledge flow in the system exhibits the emergence of a fast flow rate, a high mean value and little variance. When relationship strength is at other levels, the emergence of knowledge cannot be identified.

This paper presents the chemical and phase composition, microstructure, and selected properties both at room temperature and at the temperature corresponding to the expected operating conditions of three successive generations of TiAl-based alloys (Ti-47Al-2W-0.5Si, Ti-45Al-8Nb-0.5(B,C), and Ti-45Al-5Nb-2Cr-1Mo-0.5(B,C)-0.2Si) melted in a vacuum induction furnace with high-density isostatic pressed graphite crucibles. The obtained results of mechanical and physical properties of the produced alloys were compared to the properties of reference alloys with similar chemical composition and melted in a cold copper crucible furnace. The effect of increased carbon content in the produced alloys due to the degradation of the graphite crucible during melting is higher strength properties, lower plastic properties, higher coefficient of thermal expansion, and improved creep resistance. It was shown that the proposed technology could be successfully used in the production of different generation TiAl-based intermetallic alloys.
